Penny CRH...what should I look for?

Hey everyone, it's AmericasPennies.
I, being an novice coin roll hunter (especially to pennies) am wondering what I should look for. I went out and bought $25 worth. What should I be looking for and what do I need to find these coins (magnifying glass etc.)
I started with nickels a few weeks ago but, being a 13 year old with a small budget, I am trying pennies. again, i have absoposilutely NO IDEA what to look for!
Any suggestions would be highly appreciated. I'll give a like if you even answer.
Thanks,
Americas Pennies (JEB)
